in Garden Grove, CA |
Dr Alimadadian has been my cardiologist for the past 11 years and he has been excellent in my care.
Laguna Hills, CA |
My husband and I have both been going to Dr Alimadadian for years now. We couldn't be happier with his knowledge, expertise and care given to both of us over the years. Caught a total blockage on my husband widow maker artery and performed a stent placement some years back. Can't imagine what would have happened if he hadn't been on top of this situation. Would totally recommend Dr. Alimadadian and his attentive staff.
